IPB06N03LAT N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IPB06N03LAT is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 25V drain-to-source voltage with 50A continuous drain current in a Surface Mount TO-263-3 (D2PAK) package. This device is classified as Obsolete product status. Due to obsolescence, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPB06N03LAT is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Compatibility Parameters:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 175°C (TJ)
• Drain to Source Voltage (Vdss): Equal to or greater than 25V
• Current - Continuous Drain (Id) @ 25°C: Equal to or greater than 50A (Tc)

Electrical Performance Parameters:

• Rds On (Max): Lower or equal values indicate improved performance
• Power Dissipation (Max): Equal to or greater than 83W (Tc)
• Gate Charge (Qg): Lower values preferred for switching efficiency
• Input Capacitance (Ciss): Lower values preferred for gate drive requirements

The substitute parts listed below meet or exceed all mandatory compatibility parameters and are qualified as direct functional replacements for the obsolete IPB06N03LAT.

Engineering Selection Recommendations

PSMN4R3-30BL,118 (Nexperia USA Inc.) - Primary Substitute

The PSMN4R3-30BL,118 is the recommended primary substitute for the obsolete IPB06N03LAT. This part is in Active product status, ensuring long-term availability and supply chain continuity. It exceeds the mandatory current rating (100A vs. 50A) and power dissipation (103W vs. 83W), providing design margin for thermal and electrical performance. The Vdss rating of 30V exceeds the original 25V specification. RoHS3 compliance and REACH Unaffected status meet modern regulatory requirements. The lower Rds On value (4.1 mOhm @ 15A, 10V) indicates improved efficiency compared to the original part.

PSMN017-30BL,118 (Nexperia USA Inc.) - Secondary Substitute

The PSMN017-30BL,118 is classified as Obsolete product status. While it meets package and thermal requirements, the continuous drain current rating (32A) falls below the original specification (50A). This part is suitable only for applications where the actual operating current does not exceed 32A. The higher Rds On value (17 mOhm @ 10A, 10V) results in increased power dissipation and reduced efficiency. RoHS3 compliance and REACH Unaffected status are maintained.

Selection Criteria:

• For new designs and production requiring long-term component availability: Select PSMN4R3-30BL,118
• For applications with continuous drain current ≤ 32A and where obsolete parts are acceptable: PSMN017-30BL,118 may be considered
• All substitute parts maintain identical package geometry (TO-263-3, D2PAK), operating temperature range (-55°C to 175°C), and gate voltage specifications (±20V)

Frequently Asked Questions (FAQ)

Q1: Can PSMN017-30BL,118 be used as a direct replacement for IPB06N03LAT in all applications?

No. The PSMN017-30BL,118 has a continuous drain current rating of 32A, which is below the IPB06N03LAT specification of 50A. This part is suitable only for applications where the actual operating current does not exceed 32A. For applications requiring the full 50A capability, PSMN4R3-30BL,118 is required.

Q2: What are the key differences between the two substitute parts?

The primary difference is current handling capacity. PSMN4R3-30BL,118 is rated for 100A continuous drain current with 103W power dissipation and Active product status. PSMN017-30BL,118 is rated for 32A continuous drain current with 47W power dissipation and Obsolete product status. Both parts share identical package geometry and thermal operating range.

Q3: Are the substitute parts pin-compatible with IPB06N03LAT?

Yes. All three parts use the TO-263-3 (D2PAK) package with identical pin configuration: 2 leads plus tab. No PCB layout modifications are required for package compatibility.

Q4: What is the impact of the higher Vdss rating (30V) on circuit design?

The higher Vdss rating (30V vs. 25V) provides additional voltage margin and does not negatively impact circuit operation. The device will function correctly in circuits designed for 25V operation. No circuit modifications are necessary.

Q5: How do the Rds On values affect power dissipation?

Lower Rds On values result in lower conduction losses. PSMN4R3-30BL,118 has Rds On of 4.1 mOhm (improved efficiency), while PSMN017-30BL,118 has 17 mOhm (higher losses). For high-current applications, PSMN4R3-30BL,118 will generate less heat and improve overall system efficiency.

Q6: Are there any compliance or regulatory differences between the parts?

PSMN4R3-30BL,118 and PSMN017-30BL,118 are both RoHS3 Compliant and REACH Unaffected. The original IPB06N03LAT compliance status is not specified. Both substitute parts meet current regulatory requirements for new production.

Q7: What is the significance of Active vs. Obsolete product status?

Active product status (PSMN4R3-30BL,118) indicates ongoing manufacturing and long-term availability. Obsolete status (PSMN017-30BL,118 and IPB06N03LAT) indicates discontinued production with limited remaining inventory. For new designs, Active parts are strongly preferred to ensure supply chain continuity.

Q8: Can these parts be used interchangeably in existing designs?

PSMN4R3-30BL,118 can replace IPB06N03LAT in all applications. PSMN017-30BL,118 can replace IPB06N03LAT only in applications where continuous drain current does not exceed 32A. Verification of actual operating current is required before selecting PSMN017-30BL,118.
